[Interesting! MTN must have released it so recently that nobody has located the SBF. EMEA means Europe, Middle East, Asia... so it's probably UMTS 900/2100. Don't forget to take a nandroid backup now before trying anything - because you may have no way to get back to your original carrier's firmware.

Also if anyone else on your carrier buys a Milestone and is looking to root, suggest that they make the backup before rooting. Then there will be a master copy.]

3Plug the USB and shut your Milestone down.

4Boot it in bootloader mode.

[press the D-PAD UP key while pressing the power button]

5Windows will start installing some driver. When done Launch RSD lite. The name of your beloved device.

6Select the SBF file you downloaded. Hits "start". The phone will reboot several time. And once succeed it will say PASS
